Industrial Applications of TERT-BUTYL PROPIOLATE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used in the synthesis of alkyne-containing drug molecules, such as protein kinase inhibitors and antitumor compounds | Employed as an alkynylating reagent in palladium-catalyzed cross-coupling reactions (e.g., Sonogashira coupling) |
| Pesticide Development | Serves as a structural motif in novel insecticides and fungicides; incorporation of the tert-butyl group enhances lipophilicity and metabolic stability | Applied in derivatization reactions—including ester hydrolysis, amidation, and cycloaddition—to construct active molecular scaffolds |
| Materials Science | Used as a functional monomer for synthesizing alkyne-containing heat-resistant polymers and crosslinkable coating materials | Participates in click chemistry (CuAAC) or thiol–alkyne addition reactions to enable controlled polymerization or surface modification |
Manufacturing Quality Control of TERT-BUTYL PROPIOLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities remaining after high-temperature combustion of sample. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with water and air. |
| Refractive Index at 20 C | Refractometry | Measures bending of light passing through sample to determine purity and composition based on Snell's law. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using suppressed conductivity detection after anion exchange separation. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Residual Solvents (e.g., MeOH, THF) | Headspace Gas Chromatography (HS-GC) | Detects volatile solvents by analyzing equilibrium vapor phase above sample using GC-FID or GC-MS. |
| Alkali Metals (Na, K) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures elemental emission intensities after plasma atomization and excitation of digested sample. |
| Peroxide Value | Iodometric Titration | Quantifies hydroperoxides by oxidation of iodide to iodine, followed by titration with standardized sodium thiosulfate solution. |
